NRf9160 factory restore

[RicFlair]

Hello, i recently used a gateway to sensor example and am unable to revert back to factory program of nrf9160 DK. 

I toggled the switch 5 to nrf52840 and flashed the first program and then toggled back to nrf9160 and flashed it with the other. 

I am trying to revert back by erasing nrf9160 and nrf52840 using programmer from nrf connect app. 

I used secure boot for nrf9160 part but what can i use for nrf52840? 

Also, what is the placement of  switch 5 by default? Nrf9160 or nrf52840? 

I am trying to get back to it’s original state as all worked well with asset tracker previously  but now if i try and program nrf9160, I have a memory location issue. 

Thanks!

On the nRF52840 we are by default using a board controller(nRF9160 DK board controller firmware). You can download the hex from this link.

Default is nRF9160.
